Raspberry Pi Zero Wireless
I have a Pi Zero connected to a breadboard using the GPIO Extension Board and ribbon cable.
I have followed several of the basic blinking LED tutorials.
One jump cable is connected to GPIO22. When I run the basic program:
from gpiozero import LED, Button from time import sleep led = LED(22) while True: led.on() sleep(1) led.off() sleep(1)
If I touch the jump cable to
3V3 the LED lights. So, I figure the circuit is a happy one. If I touch the jump cable to
RXDO the LED blinks, as expected.
Any ideas why this might be?
Update: So, it's quite interesting. The connection between the end of the ribbon and the Pi is not secure. There's a bit of wiggle-room. If I apply a small amount of pressure one way, vs the other, the power seems to travel a slightly different path.
